For each subject, the ultimate GSK690693 price performance factor was calculated as the mean of the normalized

VO2max, Wmax and 5-min test mean-power performance values. Ingestion of the three supplements CHO, PROCHO, and NpPROCHO did not provide differences in HR, VO2, or RER at 30 min, 60 min, 90 min, or 120 min of the prolonged submaximal cycling (Table 2). Nor did the three beverages result in differences in blood glucose and blood lactate (Table 3) or in RPE (mean values ranging from 11.1 to 13.5 across time points and supplements during the prolonged cycling; data not shown). The supplements did, however, result in differences in the concentration profile of BUN. While ingestion of CHO did not selleck compound result in changes in BUN levels between baseline (6.3 ± 1.5 mM) and 120 min (6.7 ± 1.8 mM) of steady-state cycling, ingestion of PROCHO and NpPROCHO resulted in changes from 5.9 ± 1.1 mM to 7.7 ± 1.8 mM (P < 0.017) and from 6.1 ± 1.5 to 7.5 ± 1.9 mM (P < 0.0003), respectively (Table 3). The NpPROCHO beverage was associated with higher BUN values after 120 min of cycling than the CHO beverage (P < 0.017), an effect that was not quite found

for the PROCHO beverage (P = 0.03) (Table 3). No difference was found between PROCHO and NpPROCHO beverages (P = 0.44).
